It would be hard to imagine a greater contrast between today's launch by Canon of its EOS C300 digital cinema camera and the launch of RED's long-awaited Scarlet. Canon's event was huge and long-winded with a string of cinematography heavyweights on stage. At the RED gathering half an hour later, an ad hoc bunch of the faithful turned up at RED studios, ostensibly just to watch the same web page update as the rest of the world. Alas it didn't quite work out like that.
